T 0 all whom it may concern:

Be it known that 1, Dennis QUINLAN, a citizen of the United Statesyresiding at Blue Plains, in the District of Columbia, have invented certain new and useful Improvements in Fastening Devices; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it use the same. t

This invention relates to fasteners, and

appertains to make and more particularly to a cincture for the etfia cient and ready securing together of sepa} rate bodies and consists of: a pairof complemental or reclprocal units capable of being interlocked with each other when Inutually related to secure thebinding together of the bodies. a

It is an object of the presentinvention to provide an extremely simple, practical and inexpensive, substantial, durable and easily applied cincture or stitch-likefastening device. It is furthermore an object of this invention to provide a cincture or thread-like stitch or fasteningmeans ca pable of being applied with facility without the requirement ofany special treatment or altering of the bodies tobe-secured andwithout the necessity of the applica tion of any special tools and which at the and substantial fastener. l j i It is an important object of the present invention to provide a cincture consisting of a pair of duplicate reversible intersame time provides an entirely satisfactory changeable units which become reciprocal i 0 preferably bemg mummy Pointed, as at 4, to

to form a complete cincture or stitch-like girdle to encompass or secure two or more separate bodies 1n desired assembled relation, and a further object is to provide units which will be mutual in their co-action as units one upon the other to bring them to their respective places of rest without careful measurements or peculiar tools, each of the units being so designed and constructed that they cooperate one with the other to secure the final assembled relation together.

With these and other objects in view, the invention consists in the construction, the combination, and in details and arrangements of parts as more particularly described hereinafter relative to the embodiments of the invention described in the folspeeifiafion q a s amt, Patented J1me 2a, 191s. Application filed January 15, 1919. Serial No. 271,310.

lowing specification and illustrated in the accompanying drawlngs, in which: Figure 1 1s a perspective View of a fragment oftwo strap ends secured bythe im- 3 proved fastening, the strap ends being in section to illustrate the fastening in side elevation;

2 an enlarged detail view of the cincture or fastening device partly broken away to illustrate clearly the interlocking of the units by riveting;

Fig; 3 is an enlarged detail sectional view of the overlapped strap ends in section and showingthe units of the cincture in assembeing constructed of units which may differ in various particulars and details, the general princlple covering the construction of the complete cincture orfastcner involvesa pair of unit members in the form of staples as shown in Fig. a 4, these staples being made of any suitable material and of material of any suitable cros sectional form and other outline, in the present instance each staple or unit 2 comprising a transverse or corn nectinlg bar 8; having a pair of parallel or substantially parallel legs 3--3 which preferably have their inner or opposed faces plane, as indicated, the ends of the legs facilitate the penetration by the legs of the material, such for instance the overlapped ends S. A feature of the present invention resides in perforating or having at one end of the transverse bar 3 of a unit an aperture 5, one side of which preferably lies close to the plane of the inside surface of one of the legs 3, so that after one of the units has been driven through the bodies to be connected or securely fastened then a mutual or reciprocal staple or unit member going to complete the cincture may be positioned withits points substantially in contact with complemental points and surfaces on the inserted unit 3 (see Fig. 3, dotted lines), whereupon the second unit 3 may be driven with its points disposed oppositely to the previously driven unit, the legs of each of the units being mutually complementary to the other and therefore acting as units to direct the movement of the penetrating legs through the material to be secured together and finally so that the points of the legs which happen to be in a position inside or between the legs of the reciprocal staple are directed accurately and may be driven rapidly through the complementary aper ture 5 provided therefor, in each of the transverse bars 3 of the staple units. After the units going to form the complete coupling or cincture have been driven completely home as shown in F 3, those points of the staple legs which have penetrated the openings 5 and extend beyond the tops of the staples are designed to be clippedofl as at a, Fig. 3, and then riveted close down while the:point of the'legs of the staplesremaining outermost in the complete cincture may be clipped off close down to the surface of the connected bodies, as at Z).

From the above, it will be seen that I have provided a cinctureor girder orcloscdfinjetallic stitch which will efficiently connect two separate bodies and which are designed to be mutual in their co-action as guides one on the other to-facilitate the driving of the units to their final position of rest and connecting thebodies.

A slightly modified form of the body structure of'the unit is illustrated in Figs. 5 and 6, in which case the bodies of-the material of the transverse bar 3 are shown as laterally enlarged, as at 3 around the apertures 5 in ordertopreservezand maintain the maximum strength of thelinished unit. Obviously the finished unit or staple has its-legs folded down substantially perpendicular -to thep-lane of the'bar 3, the fold being made approximatelyon the line f'f perpendicular to the axis of the blank (see'Fig. 5) so-that at one side the opening is substantially in the plane of the inside surface of the perpendicular leg.

lVhat is claimed is:

1. A cincture unit consisting substantially, of a common wire staple with a straight cross-bar which is perforated on an axis parallel to the legs of the staple, the perforation having one side in the plane of the inside surface of one of the legs whereby said surface will act as a guide for a complementary unit of similar character when the units are being assembled. o

2. A ein-cture unit consistingsubstantially, of acommon fiat wire staple with astraight cross-bar which is perforated on anaxis parallel tothe legs of the staple, the perforation having one side in the plane of the inside surface-of one-of the legs whereby said-surface will act as a guide for a complementary unit of similar character when the units are being assembled.

3. A cincture consisting of a pair-0f duplicate and. interchangeable wire staples each having a straight-cross bar which is perforatedon an axis parallel to the legs of the staple, the perforation having one side in:the plane of the inside surface ofone of. the-legs so that said surface will act as a guide for a-compleinentary unit of similar character when the units are being as sembled.

el. Acincture consisting of a pair of duplicate and vin:terchangeable wire staples each having a straight crossbar-which isaperforated on anaxis parallel to the legs of the staple, theperforation having nne side in the plane-oftheiinside surface of one of the legs so that said surtaeev will aettas a guide for a complementary unit of similar character when :the units are being-assembled, the points of the legs which extend through the respective, reversely disposed unitsbeifllg clippedflush and riveted.

In testimony whereofI a'flix my signature.
